Hi,
What could be causing the following issue when running "mpiexec.exe -validate -host localhost"
[mpiexec@HOST0004] validate_fn (..\windows\src\mpiexec_params_init_win.c:290): server rejected credentials on host localhost

ref: IMPI version, hydra registered, credentials cached, I even tried "C:\>klist purge"

C:\>"%I_MPI_ONEAPI_ROOT%\env\vars.bat" has no output (blank line)

C:\>"%I_MPI_ONEAPI_ROOT%\bin\mpiexec" -version

C:\>"C:\Program Files (x86)\Intel\oneAPI\mpi\2021.5.1\bin\hydra_service.exe" -installIntel(R) MPI Library Hydra Process Manager 2021.5 installed.

Hi,

Thanks for reaching out to us.

We tried at our end using Intel MPI Library 2021.5.0 on a windows machine using the below steps and it worked fine.

Use the following commands to determine the user names and domain names of your machine.
> whoami domain-name\user-name
Next, invoke the following commands to set up the Hydra process manager:
> hydra_service -start > mpiexec -register domain-name\user-name password confirm password > mpiexec -validate SUCCESS
Note: Please make sure to give "account (domain\user)" name for mpiexec -register as "domain-name\user-name" which is the output of "whoami" from step 1.

For more information regarding the steps, please refer to the link:

https://www.intel.com/content/www/us/en/developer/articles/training/micro-cluster-setup-with-intel-mpi-a-stepwise-guide-to-setting-up-the-smallest-windows.html

Please try the above steps and let us know if it works. If this resolves your issue, make sure to accept this as a solution. This would help others with a similar issue. Thank you!

Best Regards,

Santosh

Hi Santos,

Thank you for reaching for a status - your commands were the same as we had done prior.

"%I_MPI_ONEAPI_ROOT%\env\vars.bat"
hydra_service -install
hydra_service -start
mpiexec -remove
mpiexec -register
mpiexec -validate

Validate still fails with the same:

validate_fn (..\windows\src\mpiexec_params_init_win.c:290): server rejected credentials on host Hostname

Hi,

Could you please provide your environment details( CPU & its version)?

We have several different Windows machines.

Below is the processor details for some.

Hi,

>>" validate_fn (..\windows\src\mpiexec_params_init_win.c:290): server rejected credentials on host <hostname>"

We will get the above error only if we give the wrong credentials. Please follow the below steps for 'mpiexec -validate':

The value of 'domain-name\user-name' must be the same as the output of 'whoami' command.
The password must be the one with which you log in to your machine.

If you still face the issue, then try to skip the command 'mpiexec -validate' and try to run a sample MPI application. While running an MPI program, If it prompts you to give a username & password, then give it a try and let us know if you can able to run a sample MPI program.

Also, could you please check whether you are using a supported windows target machine by referring to the below Intel MPI system requirements page?

URL: https://www.intel.com/content/www/us/en/developer/articles/system-requirements/mpi-library-system-requirements.html

If you are not using a supported target operating system, then we recommend you use any one of the supported target OS and try again.

Thanks & Regards,

Santosh

I'm using Windows Server 2019 which is supported.

When I'm registering my regular account the validation fails.

When I'm registering my admin (elevated) account then validation is successful.

This is regardless of how I logged into the machine and the "whoami" command output.

Seems like it has something to do with permissions.

I'm running mpiexec -n 2 -ppn 1 -hosts <hostnames> hostname for testing and it fails after I register my regular account

Looks like the problem was resolved after I added the user account to "Remote Management Users" group under Computer Management -> Local Users And Groups

Thanks for the support
